[PD] PD] request assistance with crackles and pops using wiimote

[Julian Brooks]

Hi Darren/list,

I'm currently experimenting with the wiimote.

I'm having similar problems with crackle/noise, any suggestions much
appreciated.

Something preferably before we get into the audio domain.

Cheers,

Jb

driven, by modulating accelerometer signals

Hi PD list,

I have uploaded an example of the problem as about 20 rather unmusical 
seconds of me waving 1 Wiimote
as accelerometer driving frequencies of 3 [osc~], almost nothing else 
running, and no visuals, sliders, atoms:

ackles.mp3

It is panned quite left (when I use 2 Wiimotes I pan them leftish and 
rightish).

Will keep breaking it down further to isolate the problem.

The patches including visuals (now disconnected) can be viewed at:
